I am trying to use F() statement inside ordering in model:
{{{
class MyModel(models.Model):
owner = models.ForeignKey(settings.AUTH_USER_MODEL, blank=True,
null=True)
created = models.DateTimeField(db_index=True, auto_now_add=True)
class Meta:
ordering = (F('owner_id').asc(nulls_first=True), 'created')
}}}
and this causes an error when running manage.py:
{{{
[...]
File "/[...]/lib/python3.6/site-packages/django/db/models/base.py", line
1651, in <genexpr>
fields = ((f[1:] if f.startswith('-') else f) for f in fields)
AttributeError: 'OrderBy' object has no attribute 'startswith'
}}}
